I've always wanted a way to to make sight adjustments to my Aimpoints without having to remove the turret caps and being stuck using a special tool. I came up with an idea I thought would work and approached Roger Wang of Forward Controls to see if he'd be interested in developing it. He was and he did. Forward Controls has recently released their new ATA Cap kit. The kit comes with two outer caps and two turret discs. (Please ignore the disc. I ordered two kits, one with silver discs and one with black discs. Somehow, the black disc found its way into the photo.) They're easy to install. Just remove the factory caps, place the turret disc on the adjustment turret so the pins line up with the pin detentes and screw down the outer cap Done! Now all sight adjustments can be made without ever having to remove the caps or using a special tool. Adjustments are smooth and can be made with a common screwdriver, coin or the rim of a case. Clicks are positive and easy to count. The slot is also a good visual indicator as changes are made. Only the disc turns when adjustments are made. The outer cap remains stationary. There is little chance that a bump to the caps will change the adjustments https://wolfhollow.smugmug.com/F1/ATA-VID/n-4fXwQL/i-grFz98x The cap & disc are made of stainless steel and QPQ coated. Machining is top notch. Roger sent the ATA caps along with an Aimpoint Micro and the factory caps to a lab to see how well they sealed against moisture. The ATA caps work just as well as the factory caps. I fixed my two Micros with the ATA caps and I think they're awesome! (I'm also excited to see an idea of mine developed and brought to market and might be a bit biased) The design is simple and elegant and work better than I hoped for. Roger deserves a lot of credit for taking my idea and making it better. You can check them out at the Forward Controls website. What do you think?
